Pepper yellow vein disease (PYVD) has been reported to be associated with the African monopartite begomovirus Pepper yellow vein Mali virus (PepYVMLV) in West Africa (Tiendrébéogo et al., 2008; Zhou et al., 2008). Recently, vegetable isolates of PepYVMLV have also been shown to be associated with a DNA-B component in Burkina Faso (Ouattara et al., 2019) and Cote d’Ivoire (Soro et al., 2021). In September 2021, severe leaf yellowing, curling and deformation symptoms, resembling those of pepper yellow vein disease were observed on tobacco (Nicotiana tabacum) bordering pepper and tomato fields in Burkina Faso. Molecular diagnosis and bioinformatic analysis show the detection of both DNA-A and -B components of PepYVMLV from tobacco with high similarity with previously characterized isolates from West Africa. To our knowledge, this is the first report of PepYVMLV naturally associated with tobacco yellow leaf curl disease in Burkina Faso and globally. Our results highlight the potential existence of alternative natural hosts for PepYVMLV.
